SPECIFICATION forming' part of Letters Patent No. 702,417, dated J' une17, 1902.

Application tied April 6, 1901.

10 (tu tuff/O77?. it' mot-y concern:

Be it known that we, WILLIAM GATES, residing at Woodbridge, and LouisWILLIAM GATES, residing at Orange, in the county of New Haven and Stateof Connecticut, citizens of the United States,`have invented certain newand usefullmprovements in Valves, of which the following is aspecification.

This invention relates to appliances adaptlo ed for use in drawing offliquids from containing vessels, and more particularly tostraightway-valves designed for use in drawing olf lager, ale, and thelike from casks, kegs, or barrels.

In dispensing beer, ale, the., to the consumer it is a common practiceto effect the discharge of the liquid through a valve-controlled passagecommunicating with the keg, cask, or other` vessel in which it is storedthrough the tension exerted by carbonio-acid gas, air, &c., admittedunder pressure to the vessel and serving to elevate ythe liquid througha pipe extending some distance below the surface of the liquid.

The present invention has for an object to provide an appliance simplein form and of cheap construction whereby access may be had to theinterior of the keg, &c., for the insertion of the pipe or conduitthrough which the liquid is to be discharged; and theinvention provides,furthermore, an appliance that may be permanently secured to the keg andhas no projecting parts liable to breakage or injury duringtransportation. y

Referring to the drawings which accom; pany the present specificationand whichillustrate an embodiment of our invention, Figure lis partly anelevational and `partly a sectional view representing in place an ap- 4opliance of theL foregoing character constructed according to ourinvention. Fig. 2 is a longitudinal section thereof on asomewhatenlarged scale and shows in connection with the valve proper andvariousparts a key for 45 operating the former. Fig. 3 is a top View ofthe appliance, the key shown in Fig. 2 being removed and the passagethrough the former being open.

Fig. 7is an elevational view of the valve-casing with theguard-piece shown in Fig. 5 in the position it occupies when the openingthrough the appliance is closed. Fig. 8 is a perspective view of asliding plate embodied in the appliance and constitutingthe valveproper. Fig. 9 is a similar view of the valve-casing. Fig. 10 is asimilar View of the Aguard-piece. Fig. 1l is an elevational view of akey adapted for openingand closing the passage way through theappliance. y

Similar characters of reference designate corresponding parts in allfigures.

An appliance constructed according to the present invention isparticularly adapted for permanent attachment to a cask, keg, or othervessel used for holding beer, ale, and otherbeverages, and itsconstruction embodies no projecting parts liable to injury or damageduring handling or transportation, providing, furthermore, astraightway` opening into the keg, dac., through `which thedischarge-pipe for emptying the former may be inserted. Means also existfor the attachment of a conduit or pipe delivering carbonio-acid gas,air, or other fluid utilized for exerting a pressure upon the liquidwithin for the purpose of elevating the saine through the inserted pipe.

The appliance is shown in Fig. l of the present drawings secured to thehead of a keg A of liquor, and it comprises a tubular body portion(designated in a general wayby B) adapted to be secured in a suitableopening in the vessel in any desired manner, the connection here showncomprising a screw-thread b on the outer` surface of the bodyportion, bywhich means the latter is adapted to be screwed into the vessel until itabuts against a shoulder b', formed by a flange on the body portion andpreferably entering a countersunk recess to bring the outer-face of thebody portion substantially flush `with the outer surface of the head, asindicated in Figs. l and 2.

The valve proper of the appliance serves to control the continuity ofthe passage through the bore of the body-piece and in the preferredconstruction is mounted in a valvecasing, which may be attached inanydesired way to the body portion of the appliance, the provision of anindependent valve-casing facilitating the manufacture and assembling ofthe parts. The valve proper (designated in a general Way by C) isconveniently made in the form of a sliding plate, which is adapted tomove transversely to the passage through the bodyportion, being mountedin a suitable guidevvay 2, formed in the valve-casing, (designated in ageneral Way herein by D.) The guideway in the valve-casing as formed inthe present instance is a T-slot at the lower portion of the casing, thesliding plate constituting the valve having a rib 3, forming one itsguiding-surfaces. The sliding plate may beheld against its seat to forma sliding joint by some spring-like device, this device as constructedin the present case comprising springs 4 and 4, inserted between thesliding plate and overlapping portions of the guideway formed in thevalve-casing.

For operating the valve We provide avalveactuator convenientlyconsisting of an oscillatory member which serves to transmit motion fromthe operating-key (to be described) to the valve-plate and effect themovement of the lat-ter in its guide. In the form herein shown thisactuator (designated in a general Way by E) comprises an annular part 5,Whose central opening forms part of the passage through the appliance.The actuator is mounted to rotate upon its axis in the valvecasiug,being confined to its proper movement according to the illustratedconstruction by bearing portions 6, (any suitable number,) formed in thevalve-casing, a circular flange 6 within the body portion, and the innersurface of the valve-casing. Projecting from the annular part of theactuator is a pin 7, which enters a recess 7 in the sliding or valveplate and serves to effect the movement of this valve plate when theactuator is turned upon its axis, an elongated opening 8 being providedin the valve-casing to permit of the movement of the projecting pin andhaving shoulders at its ends determining the extent of movement of thelatter. Afriction device for preventing too free a movement of theactuator is shown, consisting of a spring 9, Whose curved end isadaptedto bear against the periphery of the actuator.

A key fol-shifting the valve-plate is adapted to pass down through thebore of the body portion' and engage with the valve-actuator. Theconstruction for effecting this engagement comprises in the presentembodiment projections 1111, (two such being shoWn,) cX- tending fromthe actuator axial/ly of the bore of the body portion and adapted toengage with corresponding notches 11'11", formed at the end of the keyF. The key is hollow or tubular, and from the foregoing description itis evident that When inserted in place and turned upon its axis theresulting movement of the actuator Will effect the shifting of thevalve-plate.

The key serves as a convenient means for the inlet of the pressuremedium, and for this purpose it is provided with a tubular oiset 12, towhich a conduit 13, delivering the pressure medium, may be attached.

Through the tubular key when turned to a position in Which thevalve-plate is opened and through the body and valve portions of theappliance may be passed the pipe or conduit (designated in a general wayby G) serving for the discharge of the containing liquid and whichterminates adjacent to the bottom of the vessel. This discharge-pipe Gissomewhat smaller in diameter than the diameter of the straightwaypassage to admit the pressure medium to the interior of the vessel, andfor the purpose of making a tight joint With the body-piece to prevent aleakage outward around the key there is provided suitable packing 111anda coperating seat 14 therefor. i This packing may be pressed securelyagainst the seat by providing inclined or camshaped ears 15 15 on thekey, which as the latter is insertedin place pass through correspondingrecesses 15 and 15"', respectively, in the body portion and serve bytheir coaction with coperative portions 154 155, respectively formed bycircular slots in the body portion, to press the packing firmly againstits seat. This construction also locks the key in place until it hasbeen turned back to its entering position-that is, to a positioncorresponding to a closed position of the valve-plate-and if the earsand corresponding recesses are made of different Widths pair and pair,as shown, Will permit the insertion of the key in a definite positiononly of the latter.

The tubular key is furnished at its upper or'outer portion with asuitable means for connecting it by a pressure-tight joint with thedischarge-tube G. For instance, it may be connected to the latter by acoupling 16, and the outer delivery-tube g for delivering the liquid tothe desired point may be connected directly With it, or thedischarge-tube may be provided with an attached valve 17 and a coupling(designated by 1S) utilized for secu ring the delivery-tube g to thisvalve 17.

To .prevent the forcible insertion of a discharge-pipe through theappliance With probable resultant injury to the valve-plate when thelatter is in a closed posit-ion, there is provided in the presentembodiment a guardpiece, (designated in a general Way by H,) Whichconsists of a linger provided With a pivot-pin 20, entering a pivotalrecess in the valve-casing and adapted to pass through an opening 21 inthe annular portion of the valveactuator. It will be noticed,particularly in Fig. 7, that the shoulders at the ends of this recessare somewhat curved, constituting thus a means for securing theoperation of the guard piece. When the valve-actuator is turned to aposition in which the valve-plate is closed, the shoulder 22, impingingagainst the side of the guard-piece, urges the same into a position inwhich it extends across the passage through the appliance. When, how-IOO IIO

ever, the actuator is rotated to shift the valveplate and open thepassage, the opposite shoulder operating in like manner serves toWithdraw the guard-piece from its protruding position across thepassage; but the parts are so constructed and related that the shoulder22 does not assume a position in which the guard-piece is permitted tobe withdrawn from its protruding position until the valveplate has beenmoved to substantially the end of its opening movement. Thus it will beseen that the guard-piece, which, it may be stated, is located in adifferent' plane to that which the valve-plate occupies, serves toprotect thelatter in all positions in which it extends into and acrossthe passage.

The valve-plate is shown provided with a concave notch 23 at oneend,iwhich notch is brought into alinement with the throughpassage Whenthis plate is shifted to open the passage.
